IMPROVEMENT IN WAGON-SEATS.

' Specification forming part of Letters Patent No. 136,123, datedFebruary 25, T2573.

To all 'whom it may concern:

Be it known that we, JorIN G.-AEMsTRoNG and J ACOB S. ARMSTRONG, of Reedtownship, in the county of Seneca and State of Ohio, have invented newand useful Improvements in Spring-Seats for Wagons; and do hereby4declare that the following is a full, clear, and

exact description thereof, reference being had to the annexed drawingand letters of reference marked thereon.. Y

The nature of our invention consists in the construction and arrangementof a spring-seat for wagons, as more fully hereinafter set forth. Figure1 represents a front view of our seat,

kshowing the general arrangement of its parts.

Fig. 2 is a bottom view of the same. Fig. 3 is a detail view of theblock D, with the recess K, in which the compensating-rods E Work, andthe locking-pieceA H.

The seat A maybe made in any convenientform. Across the center, on theunder side, we

attach a strip of wood, C, Fig. 1, to which we Y secure thecompensating-rods E by staples G G. The compensatingrod Eis made of onepiece, bent as shown. The two ends of rod E are turned up so as toengage the lockin g-piece H. The lockingpiece H is fitted into the blockD iiush, and is iirmly held there by the hooked plate I being screwed orbolted to block D. The hook of plate I is intended to rest and slide onthe edge of the wagon-box.

The spiral springs J are fastened at each end, respectively, to theblock D and the seat A.

The'operation of the seat may be thus de` scribed. The depression of theseat Acloses the spiral springs J, and thereby brings thecompensating-rods 'E to a horizontal plane,

causing them to require more space than in the former position. Topermit this they are longitudinally free, except so far as thelocking-piece H restrains them when withdrawn to a given point, asshownin Fig. 2.

We are aware that spiral springs have been heretofore patented, and weexpressly disclaim themas any part of our invention.

What wey do claim, and vwish to secure by Letters Patent, is

1. The compensating-rods E, the lock-piece H, and the recess K,constructed and operated substantially as described, and for the purpose set forth.

V- 2. The seat A, the spiral springs J, the strip "i C, thecompensating-rods E, the block D, theV llocked piece H, and the hookedplate 1, constructed substantially as described, and for the-purpose setforth.
